ViewRootImpl: Fix issue with early draw report in seamless rotation

When we receive RELAYOUT_RES_BLAST_SYNC from the WindowManager, we
trigger reportNextDraw, incrementing the pending draw count by one.
At the moment we unfortunately do this after dispatching callbacks
to SurfaceView. In the span of these callbacks, SurfaceView may
increment and decrement pending draw count, once it reaches zero
we will notify the WM of draw early, terminating the sync operation
without ever waiting for the ViewRootImpl to draw. By processing
RELAYOUT_RES_BLAST_SYNC before emitting the SurfaceView callbacks
we can avoid this issue.
